WHEEL- -HUB.

Specification of Letters Patent.

Patented July 25, 1905.

Application fil d January 18, 1905. Serial No. 241,674.

To all, whom, it may concern.-

object to simplify and improve the construccharacters, is illustratedthe preferred form of embodiment of theinvention capable of carrying thesame into practical operation.

In the drawings thus employed, Figure 1 is a side elevation of a wheelwith the improved devices embodied therein. Fig. 2 is a longitudinalsection of the hub portion, and Fig. 3 is a transverse section on theline 3 3 of Fig. 2. Fig. 4 is a perspective view of the axlebushingremoved. Figs. 5 and 6 are perspective views, on a reduced scale, ofmodified forms of the axle-bushing.

The improved device may be embodied in various forms of wheels employedupon various forms of vehicles employed for various purposes, but ismore particularly applicable to the train-cars and the like used inmining and like operations, and for the purpose of illustration theimprovement is shown applied to a wheel of this character; but it willbe understood that the invention is not to be limited in any manner toany particular form of wheel or to wheels employed for any particularpurpose.

The improvement consists in forming the ing into the space 17 is anoil-duct 21, covered and protected by a cap 22, held in place yieldablyby a spring 36, operating in a casing 37 and bearing against the outerend of the casing and also against a head 38 on a.

-rod 39, coupled to the cap. By this means the cap will be held withsufficient force to prevent accidental displacement under the jar ringto which the hub may be subjected when in operation.

An axle-bushing 23 is positioned in the recess 12 and provided with abearing 24 at one end for engaging the recess-bearing 14 and a bearing25 at the other end for engaging the recess-bearing 13, the sides of thebushing engaging the spaced contracted side portions 15 16 of therecess, as shown in Fig. 3. The bushing is provided with an oil-duct 26,communicating with the space 17, and an oilduct 27, communicating withthe space 18, and also provided with pin-apertures 28 29, registeringwith the pin-sockets 19 20 for receiving stop-pins30 31. The axle isprovided with the usual journal 33, engaging the bushing 23 and bearingby a collar 34: against the end bearing 25 and held in place by atransverse pin 35 in the usual manner.

To assemble the different parts of the device, the bushing 23 is firstinserted into the hub and then the pins 31 are inserted into their seats19 20 and 28 29 from within the bearing of the bushing and the journalthen inserted or the Wheel with its bushing placed over the journal, asthe case may be, the rounded inner ends of the pins 30 31 permitting theouter end'of the journal to readily pass them.

With a wheel thus constructed and equipped it is obvious that thebushing is firmly supported in position and held with suflicientfirmness to resist the strains to which it will be subjected, While atthe same time readily removable when worn or broken, so that the life ofthe wheel can be prolonged materially or until the rim or other partsare worn or broken. The greatest strains and the largest amount of wearcoming upon the axle-bearings, it is obvious that the ability to easilyand quickly renew the parts subject to the.

greatest wear and friction is an important consideration, and theimproved structure herein described and shown provides a ready means foraccomplishing this desirable result.

,The relatively large spaces 17 18 within the hub at oppositesides ofthe bushing serve as reservoirs to hold a relatively large quantity ofthe lubricant and supply it to the aXlejournal as fast as requiredthrough the feedducts 26 27, as will be obvious. The spaces 17 18 arethus important features of the invention and add materially to the valueand effectiveness of the invention.

The bushing will preferably be square or oblong in transverse section,as shown in Figs. 3 and 4, but may be cylindrical, as in Fig. 5, ortapering, as in Fig. 6, if found necessary; but this would not be adeparture from the principle of the invention, as the same results wouldbe produced in substantially the same manner.

Having thus described the invention, what is claimed is l. Awheel-hubhaving a longitudinal recess with a relatively contractedhearing at one end and a relatively large bearing at the other end, andwith oppositely-disposed pin-sockets in the side walls of the recess,an. axle-bushing for position in said recess and with bearings at theends for engaging the bearings at the ends of said recess and providedwith oil-apertu res and with pin-apertures for registering with saidpin-sockets, and stop-pins for position in said alined apertures to forma coupling means between the bushing and hub.

2. A wheel-hub having a longitudinal recess and with bearings at theends and with lateral pin-sockets intermediately of the bearings, anaxle-bushing for position in said recess and provided with bearings atthe ends for engaging said recess-bearings and with pin-apertures forregistering with said pin-sockets, pins engaging said sockets andextending into said pin-apertures, said hub having an oil-duct leadingthereinto for supplying lubricant to said recess and the interior ofsaid bushing.

3. A wheel-hub having a longitudinal recess with the walls contracted attwo sides and with bearings at the ends and lateral pin-socketsintermediately of the bearings, an axle-bushing' for position in saidrecess and engaging the contracted walls of the same and provided withbearings at the ends for engaging said recess-bearings and withpin-apertures for registering with said sockets, pins engaging saidsockets and extending into said pin-apertures, said hub having anoil-duct leading cess and bushing.

In testimony that we claim the foregoing as our own we have heretoatfixed our signatures in the presence of two witnesses.
